How to reset EWS administrator password (PIN)? I changed the pin earlier and forgot it. Now I can't enter the system control panel. Model: HP LJ M234SDWE

I had a hard time finding the instructions from the original source, from the manufacturer. But I managed to catch the moment when you need to press the Resume button to start the process +100500 times. You can't think of more idiotic ways. Is it so difficult for the developers to just make a Reset button on the back of the printer?

If you pressed this button a little earlier or a little later, you can miss and the return process will not be launched. You can suffer trying to catch the moment.

Restore factory defaults using the LaserJet MFP M232-M237 printer control panel.

1. Disconnect the printer power cord.

2. Depending on your printer, use the control panel buttons to start the factory restore.

- Printers with a flatbed scanner only (sdn, sdw, sdne, and sdwe models): Reconnect the power cord, and then press and hold the Resume button until the Status light blinks.

- Printers with a document feeder (d, dw, dwe models): Press and hold the Resume button , and then reconnect the power cord while pressing the button.

3. Release the Resume button when the Attention or Cancel light turns on and an nv message displays on the control panel.

After about 20 seconds, your printer automatically restarts.
